摘要: The present work utilizes classical molecular dynamics simulations to investigate the covalent functionalization of carbon nanotubes (CNTs) and their interaction with ethylene glycol (EG) water molecules. MD simulation reveals dispersion functionalized prevention aggregation in aqueous medium. Further, residue-wise radial distribution function (RRDF) atomic (ARDF) calculations illustrate extent –OH –COOH CNTs molecules non-functionalized CNT surface EG. As presence number increases, enhancement propensity for can be observed. However, same trend decreases EG In addition, ONIOM (M06-2X/6-31+G**:AM1) have also been carried out on model systems quantitatively determine energy (IE). It is found from these that relative highly favorable when compared
